The Norton 20X flap disc features extremely durable zirconia alumina abrasive. The overlapping abrasives provide significantly more area of abrasive when compared to standard flat sanding discs. Unlike drill mounted abrasive wheels, this disc is designed for the high speed of an angle grinder. No tools are needed to install or remove the disc because the Speed-Lok® spin on, spin off design. The coarse 40 grit disc is used for aggressive rust removal while the 60 grit and 80 grit discs are used for finer work. 4.5" diameter disc.
